Factory Quality Inspection: CBB61 4μF Capacitor Passed Random Capacitance Testing

Maintaining stable electrical performance is one of the most important requirements for AC fan capacitors. At EVA Electronics, every production batch undergoes strict quality inspection before shipment to ensure consistent product performance and long-term reliability.

This week, our quality control team carried out a random inspection on a bulk production order of CBB61 4μF capacitors. Using a professional digital capacitance measuring instrument, the selected samples were tested according to our factory quality control procedures.

Random Inspection Results

The tested capacitor showed the following performance:

• Product Model: CBB61 Capacitor
• Rated Capacitance: 4.0μF
• Measured Capacitance: 4.12μF
• Dissipation Factor (Loss): 0.0006
• Inspection Result: Qualified

The measured capacitance falls well within the product tolerance, while the extremely low dissipation factor demonstrates excellent dielectric performance and low internal energy loss. These indicators confirm that the capacitor meets our quality standards before shipment.

Why Capacitance Testing Matters

Capacitance accuracy directly affects the starting torque and operating efficiency of motors used in ceiling fans, exhaust fans, ventilation systems, and other household appliances.

Every qualified capacitor helps ensure:

• Stable motor starting performance
• Consistent operating efficiency
• Reduced heat generation
• Longer service life
• Reliable performance under continuous operation

For this reason, random sampling inspection is performed throughout production to verify that every batch maintains consistent electrical characteristics.
